Have you turned on mobile access point on your smartphone Samsung, Xiaomi or Google Pixel, but the laptop stubbornly refuses to connect to the distributed Wi-Fi? The problem is familiar to millions of users - according to data StatCounter, every fifth request to Android technical support is related to a non-working Internet connection. In 80% of cases, it is not hardware faults that are to blame, but incorrect settings or protocol conflicts.

In this article we will look at all possible reasons - from a banal limitation on the number of connected devices to hidden energy saving parameters in Windows 11that block the connection. You will receive diagnostic checklists, a Wi-Fi protocol compatibility table, and instructions with step-by-step screenshots. We will pay special attention new problemsthat appeared after updates Android 13/14 and Windows 11 23H2.

1. Checking the basic settings of the access point on Android

Before digging deep into the laptop settings, make sure that the problem is not on the smartphone side. Let's start with the obvious - the parameters of the access point itself. Open on your phone Settings → Network and Internet → Access point and modem (the path may differ depending on the shell).

Here is what you need to check:

  • 🔄 Restart the access point: turn off and on the distribution again - this will reset temporary failures in the module Wi-Fi.
  • 🔐 Password: make sure that it does not contain Cyrillic characters or spaces (some laptops do not process such combinations correctly). Try changing it to a simple Latin set, for example 12345678.
  • 📶 Frequency range: if your laptop is older than 2018, it may not support 5 GHz. Switch the access point to 2.4 GHz in the additional settings.
  • 👥 Device restrictions: some firmware (for example, on Realme or Oppo) by default block the connection of more than 2-3 gadgets simultaneously.
💡

If you Samsung with One UI, hold down the "Mobile hotspot" icon on the main screen - this will open hidden energy saving settings for the Wi-Fi module.

On Xiaomi and Redmi there is a separate problem: the system can automatically turn off the access point after 5-10 minutes of inactivity. To fix this:

  1. Go to Settings → Battery and performance → Battery management.
  2. Find the application Settings (or Access point) in the list and install for it mode No restrictions.

2. Problems with Wi-Fi drivers on a laptop

If a laptop sees network from the phone, but cannot connect (writes “Could not connect to this network” or “Limited access”), the network adapter drivers are to blame. This is especially true for devices on Windows 10/11 after major updates.

How to check:

  1. Click Win + X and select Device Manager.
  2. Expand the branch Network adapters.
  3. Find your Wi-Fi module (usually contains the words Wireless, Wi-Fi or the name of the manufacturer: Intel, Qualcomm, Realtek).
  4. If there is a yellow exclamation mark next to the name, the driver is not working correctly.

Solutions:

  • 🔄 Update driver: right-click on the adapter → Update driver → Automatic search. If Windows says that the driver is up to date, download it manually from the laptop manufacturer's website (Lenovo, HP, Asus).
  • 🗑️ Uninstall the current driver: right click → Remove device → restart the laptop. The system will install the driver again.
  • ⚡ Roll back to the old version: if problems started after the update, select Properties → Driver → Rollback.
List of problematic drivers for Wi-Fi

Users leave the largest number of complaints about drivers:

- Realtek RTL8821CE/RTL8822BE (often loses connection after sleep)

- Intel AX200/AX201 (conflicts with Android 13+ when distributed at 5 GHz)

- Qualcomm Atheros QCA61x4 (does not support WPA3 on some firmware)

For owners MacBook (especially on macOS Ventura/Sonoma): the problem may lie in the energy saving settings Open System settings → Battery and disable the option Battery charge optimization —it sometimes blocks connections to “unstable” networks.

3. Security protocol conflicts (WPA2 vs WPA3)

Since 2019, most Android smartphones by default distribute Wi-Fi with a protocol WPA3 —more secure, but not always compatible with older devices. If your laptop was released before 2018, it may simply not support this standard.

How to check and fix:

Protocol Support on Android Support on laptops Recommendation
WPA3 Android 10+ (default) Laptops 2019+ Leave if the laptop is new
WPA2/WPA3 (mixed) Android 11+ (configurable) All devices Optimal option
WPA2 All versions of Android All laptops Use for older devices

To change the protocol on Android:

  1. Open the access point settings.
  2. Find the item Security type or Protocol (on Samsung this may be hidden in Additional settings).
  3. Select WPA2/WPA3 or simply WPA2.
  4. Save changes and restart distribution.

WPA3 (default)|WPA2/WPA3 (mixed)|WPA2|I don’t know/have not configured-->

On Xiaomi i POCO the path to the settings may be different: Settings → Port. access point → Access point setup → SecurityIf the option is not there. - this means your firmware does not support changing the protocol (relevant for budget models on MediaTek).

4. Blocking by antivirus or firewall

Security software often perceives mobile access points as “suspicious networks,” especially if you connect to them for the first time. Antiviruses like Kaspersky, Avast or built-in Windows Defender can block the connection at the firewall level.

How to check:

  • 🛡️ Temporarily disabling the antivirus: try disabling protection for 5 minutes and connecting again. If it works, add the network to the exceptions.
  • 🔥 Windows Firewall:
    1. Click Win + R, enter wf.msc.
    2. In the left menu, select Windows Defender Firewall Monitor.
    3. Check if your Wi-Fi adapter is blocked.
  • 🔄 Reset network settings: In Windows, open Settings → Network and Internet → Reset network. On MacOS execute in Terminal: 
    sudo ifconfig en0 down && sudo ifconfig en0 up
    • 💡

    If the connection works after disabling the antivirus, do not leave the protection turned off! Add an access point to exceptions or set up a firewall rule.

    It also has a built-in firewall that can block distribution. To disable it: Android There is also a built-in firewall that can block distribution. To disable it:

    1. Go to Settings → System → Advanced → Accessibility → Firewall (path may vary).
    2. Disable the option or add application Settings exceptions.

    5. Limitations of the mobile operator

    Many operators (especially Tele2, Iota and virtual operators like SberMobile) block Internet distribution on some tariffs. Even if you have “unlimited”, the contract may contain a clause prohibiting the use of the device as a modem.

    How to check:

    • 📱 SMS notification: after switching on access points, some operators send a message about blocking.
    • 🌐 Personal account: go to the operator’s website and check the tariff conditions. Look for phrases like “distribution of traffic is prohibited” or “for personal use only.”
    • 📞 USSD command: send *100# or *111# —the response may contain information about restrictions.
    💡

    If the distribution is blocked by the operator, try using a VPN on your phone (for example 1.1.1.1 from Cloudflare). Sometimes this bypasses the restrictions, but the speed may drop.

    Workarounds (if the distribution is blocked):

    1. Change APN: go to Settings → Mobile network → Access points (APN) and create a new profile with the settings of another operator (for example, for MTS use APN internet.mts.ru even if you are on Tele2).
    2. USB modem: connect the phone to the laptop via cable and enable USB modem in the access point settings.
    3. Change tariff: some operators (for example, MTS) offer tariffs with permitted distribution for an additional fee (usually +100-200 RUR/month).

    Make sure that the "Traffic Saving" option is not activated in the Android settings|Check your balance - some operators block distribution if the balance is negative|Try to insert a SIM card from another operator (for example MTS or Beeline)|Disable roaming if you are outside your home region-->

    6. Problems with IP addressing (DHCP)

    If the laptop connects to the access point, but the Internet does not work (there is an exclamation mark on the Wi-Fi icon), the problem lies in assigning IP addresses. Most often this happens due to a malfunction of the DHCP server on the phone or a conflict with the laptop settings.

    Diagnostics and solutions:

    • 🔧 Manual IP configuration on the laptop:
      1. On Windows: Settings → Network → Wi-Fi → Manage known networks → select your access point → Properties.
      2. Scroll to IP Settings and select Manual.
      3. Set:
        • IP address: 192.168.43.100
        • Prefix length: 24
        • Gateway: 192.168.43.1
        • DNS: 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare)
  • 📱 Reset network settings on Android: Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth settings.
  • 🔄 Rebooting both devices: sometimes helps simply turning off and on the phone and laptop.

For MacOS the way to configure manual IP is different:

  1. Open System settings → Network.
  2. Select your Wi-Fi connection and click Advanced.
  3. Tab TCP/IP → Configure IPv4 → Manually.
  4. Enter the same parameters as for Windows.
Why 192.168.43.x?

Most Android devices distribute a network with a subnet by default 192.168.43.0/24, where 192.168.43.1 is the phone address (gateway), and the remaining IP is distributed between connected devices.

7. Hardware faults and rare cases

If none of the above helped, the problem may be in physical malfunction one of the devices. Here's what to check:

On the phone:

  • 📡 Wi-Fi antenna: if the phone fell or got wet, the wireless module could be damaged. Check if regular Wi-Fi is working (connection to the router).
  • 🔋 Energy saving: on some models Samsung i Huawei there is a hidden setting that turns off distribution when the battery charge is low (less than 20%). Connect the phone to the charger.

On a laptop:

  • 🖥️ Wi-Fi module: if the laptop does not see none the network, the antenna contact may have come loose or the adapter has burned out. On older models Lenovo i Acer this is a common problem.
  • ⚡ Overheating: some Wi-Fi modules (especially Realtek) switches off when overheated. Check the temperature using HWMonitor.

To diagnose hardware problems:

  1. Connect the phone to another laptop/phone - if the distribution works, the problem is in your laptop.
  2. Try connecting the laptop to another access point (for example, a router) - if not works, the problem is there.
  3. Use USB modem instead of Wi-Fi - if the Internet works via cable, the Wi-Fi module is to blame.
💡

If the laptop does not see only the access point from the phone, but connects to other networks, the problem is 99% software (drivers, Android settings or protocol conflict).

⚠️ Attention: Mobile distribution settings and operator restrictions may change. For example, from 2023 MTS and Beeline they began to block distribution on tariffs with “unlimited” Internet if the traffic exceeds 50 GB/month. Check the current conditions in your personal account or with the operator.

FAQ: Frequently asked questions

Why does the laptop connect to the access point, but the Internet does not does it work?

Is this a problem with DHCP or DNS. Try:

  1. On your laptop, manually enter DNS 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
  2. On your phone, disable the option Saving traffic in the mobile network settings.
  3. Check your account balance - some operators block data transfer if the balance is negative, even if the Internet itself is working.
How to distribute the Internet from Android to a laptop via USB?

If Wi-Fi does not work, use USB modem:

  1. Connect the phone to the laptop with a cable.
  2. On Android: Settings → Network and Internet → Access point and modem → USB modem.
  3. On the laptop, wait until the drivers are installed (you may need to download Android USB Drivers for your phone model).

Advantage: more stable Wi-Fi and consumes less phone battery.

Why does the access point turn off after 5 minutes?

This is how energy saving settings work. Correcting:

  • On Xiaomi/Redmi: Settings → Battery → Consumption management → Access point → Unlimited.
  • On Samsung: Settings → Device care → Battery → Adaptive battery mode → Disable.
  • On pure Android: Settings → Network and Internet → Access point → Timeout → Never.
Is it possible to distribute the Internet from Android to a laptop via Bluetooth?

Yes, but it is slower than Wi-Fi (max. ~3 Mbit/s). Instructions:

  1. Turn on Bluetooth on both devices.
  2. On Android: Settings → Devices → Bluetooth → Settings (⚙) → Bluetooth hotspot.
  3. On a laptop: connect to the phone as a network (in Windows via Control Panel → Devices and Printers).

Disadvantages: high latency (not suitable for video) and rapid drainage of the phone battery.

Why does the laptop see the access point, but does not connect (writes "Unable to connect")?

The most common reasons:

  • Incompatibility of security protocols (try changing WPA3 to WPA2).
  • Failure in the Wi-Fi driver on the laptop (update or roll back the driver).
  • Conflict IP addresses (configure manual IP as described in section 6).
  • Blocking by antivirus (temporarily disable protection for verification).

If all else fails, create a new access point with a different name (SSID) and password.
